Application April 24, 1953, Serial No. 350,926

3 Claims. (Cl. 20-52.2)

This invention relates to improvements in Window construction, such as, for example, is disclosed in my issued Patent #2,629,142, of February 24, 1953, wherein the sash members are movably disposed for vertical movement and lateral displacement and is adapted to be inserted between runner members vertically disposed in the window frame proper.

The present invention is designed to provide improved means for facilitating lateral displacement and vertical movement of the sash units to the desired position with a minimum of effort and to insure their safe location at positions of adjustment.

A further object of the improved invention is to provide a window construction of the type above referred to, having improved means to automatically compensate for changes in dimensions of both sash members as a result of changing humidity conditions.

A further object of the invention is to provide a construction of the character above described, wherein sash members are movably secured in the window jambs and are adapted to be readily removed therefrom and replaced with a minimum of effort, while at all times maintaining the window automatically sealed against the elements.

A further object of the invention is to provide a construction of the character above described, wherein the cost of manufacture would be appreciably reduced.

A further object of the invention is to provide a construction of the character above described, wherein, it would be impossible to remove the sashes from their Window frames on the street side, thereby, avoiding accident and burglary possibilities.

These and other advantageous objects, which will appear from the drawings and from the description, hereinafter, are accomplished by the structure of my invention, of which certain embodiments are illustrated in the drawings. It will be apparent, from a consideration of said drawings and the following description, that the invention may be embodied in other forms suggested, thereby, and such other forms, coming within the scope of the appended claims are to be considered Within the purview of the invention.

In the drawings:

Fig. l is a partly, fragmentary, horizontal, sectional view of one side of a Window casing embodying the invention;

Fig. 2 is a fragmentary, vertical, elevational, view thereof;

Fig. 3 is a fragmentary, elevational, view of another form of magnetic means for holding the sash members in adjustment;

Fig. 4 is a fragmentary, horizontal, sectional View of another form of supplementary means for holding the sash in vertically adjusted position pursuant to the invention;

Fig. 5 is a fragmentary, horizontal, sectional View of the side of a window casing opposite that shown in Fig. l, showing a form of supplementary means for holding the sash members in adjusted position therein;

Fig. 6 is a fragmentary, perspective view of movable runner members, of a form embodying the invention shown in Fig. 1.

In Fig. l of the drawings, one side of a window is shown comprising outer and inner casings 1t), 11, blind stops and filler strips 12, 13 and the window frame jamb 14. The opposite side of the window includes, sim- ICC ilarly, outer casing 10', inner casing 11', blind stop 12 and filler strip 13 and jamb 15.

Pursuant to the present invention, a pair of runner members 20, 21 are provided for jamb 14 and a runner member 22 for the jamb 15. Runners 20, 21 are,pur suant to the invention, arranged for lateral movement relative to the jamb 14. To that end, said runners are preferably provided with depending throat sections indicated at 23, 24 in Fig. 1 and means, such as screws 25, 26 fixed at both ends to the jamb 14. the shanks of such screws passing through slots 27, 28 in throat portions 23, 24 of the runners 20, 21. The jamb 14 may be provided with circular recesses 29, 30 to receive the throat sectionsy 23, 24 at the extreme limit of the leftward movement of the runners in the position of the parts shown in Fig. 1. The jamb 14 may also be provided vvith an additional recess 40 to receive the ange portions 35, 36 of runners 20, 21 for the same purpose of operation as noted for throat sections 23, 24. The runners 2t), 21 are designed to receive the sash Stiles 31, 32 of the upper and lower vertical sliding sash members 33, 34 (Figs. 1 and 2). The movable runners 20, 21 are preferably provided with means such as the flanged portions 35, 36 for registering sliding contact with each other during the relative independent movemeut of the runners 20, 21.

Preformed, elongated, flat, curved springs 37, at least one at each end, are positioned between the movable runners and the jamb 14, so proportioned and tensioned, as to normally urge the sash against the opposite fixed runner 22 under tension. The runner 22, as shown in Fig. 4, is preferably provided with a medial spacer portion 38 to guide the sash stiles 31', 32. The spring37 may be xed. as at one end 45 (see Fig. 2), to the iamb 14, the opposite free end 46 of the spring freely bearing on the said jamb. From the foregoing description, it will be apparent that each spring 37 normally urges the movable runner (and thereby the sash member with which it is associated) against the fixed runner 22. These springs will hold the sash members in any fixed position and will also automatically allow for compensation for fluctuations in dimensions of the sashes due to weather changes.

Because of the unfastened end of each spring, which is slightly turned up, these ends will slide easily against the surface of the jamb 14 against which they rest, thereby, allowing these springs to easily, automatically change their positions as may be forced upon them by the constant changes in sash sizes as said sashes contract and expand as a result of changing humidity conditions in the air. To remove the sash members, it is merely necessary to shift the same toward the jamb 14 lightly (in as much as this type of spring responds easily to pressure) until the stiles 31', 32 (Fig. 5) are clear of the /runner 22.

It will ne apparent that the invention, while shown in the drawings as applied to the use of two sash members 33, 34 in a window section, is adapted for use with only one sash member or with a different number than two, whether in vertical or horizontal sliding positions. Likewise, the flat, spring member 37, while shown secured to the jamb 14 in Fig. 2, might be freely positioned intermediate the jamb and lateral runners 20, 21. If desired, supplementary means may be used to hold the sash members in adjusted positions; such supplementary means, in the form shown in Fig. 4, which comprises a yieldable coating 47 applied to the runner 22, or any suitable yieldable material such as rubber, etc. The coating may be smooth-surfaced as shown in Fig. 4, or roughened. Any surface friction element or the yieldable coating above noted, as an alternative, may be applied to the edges of the sash stiles instead of to the runners. Laterally, slidable, latch means, indicated generally at 48, 49 in Fig. 5 and means to slidably receive the same indicated at 50, 51 in Fig. 5, may be used for the same purpose--namely, to secure the sash members in their vertically adjusted positions in supplementary cooperation with the spring means 37. These laterally, slidable, latch means may be applied to one or both sash stiles of upper and lower sash members depending upon the weight of the various sized sash members.

As shown in Fig. 2, the supplementary means to hold the sash members in adjusted position may comprise a magnet 53 on both of the sash members 33, 34 and the formation of the other members 20, 21 of metal attracted, thereto. For example, sash members 33, 34 might be provided with the magnets 53 as shown in Fig. 2 and the runners 20, 21 formed of metal, to supplcment the tension of the spring means in holding the sash in adjusted position in the runners. In the form shown in Fig. 3, the magnetic means 53 comprises a magnet which is loosely disposed in a non-magnetic housing 54, said housing being secured to the sash stiles 31, 32 as at 55 so that the magnet will be disposed in registry with the edges of the Stiles for contact with the runner which will be magnetically attracted, thereto. The housing 54 and magnet 53 may be disposed in recess 56 in the sash stiles 31, 32. When these magnets 53 are used in conjunction with the spring arrangement, heretofore, described as in Fig. 2, they may be used without the described housings 54.

The examples mentioned above are to be deemed to be illustrative only of supplementary means to assist the springs 37 in holding the sash members in adjusted positions, and also to keep vertical sliding sash from falling, should accidental body pressure be applied to the lower end of either laterally,'slidable runner.

As an alternative, the laterally, slidable runners and the fixed runners, together with their related, assisting, holding devices, may be applied in window frames in reverse positions to that as illustrated.

Tn the construction shown in Fig. 2, the magnet is loosely disposed in the mortise 56 of the sash stile and, when the sash is removed, the magnet will adhere to the runner. ln the Fig. 3 construction, when the sash is removed, the magnet will be retracted by its engagement with the housing so that it will be removed With thedsash in the instance where spring means are not use Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A window construction comprising a window frame having a pair of oppositely disposed jamb members, a

dual ixed runner extending vertically of the frame secured to one of the jamb members, a pair of independently movable, metallic runners extending vertically of the frame and disposed adjacent the opposite jamb member and movable laterally with respect thereto, a pair of sashes vertically slidable between the opposite runners, spring means interposed between each of the movable runners and its companion jamb member for normally urging said movable runner away from the companion jamb member and thereby retaining the sashes in any fixed position between the opposite runners, each sash being individually, bodily removable from the frame when the movable runners are moved independently toward their companion jamb member against the tension of the spring means, and magnets mounted in the stile edges of the sashes With their poles facing the respective metallic runners and coacting therewith to hold the sashes normally against vertical sliding movement.

2. A window of the character recited in claim l, wherein the spring means are springs having at surfaces transversely, said springs being disposed vertically between the jamb member and each of the respective, laterally movable, metallic runners.

3. A Window construction of the character recited in claim 1, wherein the sash stile edges are formed with mortises, a non-magnetic housing in each mortise, the magnets being positioned loosely in the respective housings for limited movement relative thereto, whereby the poles of the magnets will at all times be in contact with the respective metallic runners.
